The Highway Trust Fund, the federal government's primary source for financing highway, bridge and transit projects, took in $3 billion fewer in Fiscal Year 2008 as Americans drove 90 billion miles less over 11 months of the same fiscal year.
As a result of the continued decline in VMT, the Highway Trust Fund, which is primarily funded through federal gas tax receipts, collected $31 billion in revenue between October 2007 and September 2008 – $3 billion less than it collected the previous year, while federal transportation spending increased by $2 billion.
The Secretary noted that, if VMT continues to decline, the Highway Trust Fund may experience another shortfall sooner than expected. For this reason, she again urged Congress to fundamentally change the nation's approach to financing and managing transportation systems.
